Add fmrwhy to multi-echo resources

[emdupre]

Summary

Recently, @jsheunis introduced fmrwhy (https://fmrwhy.readthedocs.io/), a MATLAB package for processing multi-echo data. It would be great to include this in our documentation as a resource for the multi-echo community !

Additional Detail

I think it would need to be added here under Multi-echo processing software, but pending #677 the exact text area could be updated.

Next Steps

Open a PR to add this in 😸

@emdupre Thank you for this information! Will see if something can be combined with your toolbox.

@emdupre Thank you for this information! Will see if something can be combined with your toolbox.

That's great, @zswang-brainimaging ! Glad to hear that it's useful to you. If you're primarily working in MATLAB, fmrwhy seems like an especially important resource.

It's always challenging to integrate MATLAB and Python environments, but if you find a path using both fmrwhy and tedana that's useful for you, definitely let us know !

I'm trying to go through old issues to see what we can address. I can definitely add fmrwhy to the docs, but it looks like it hasn't had any commits in over a year. Since we regularly get questions on using multi-echo data with SPM it's very worth adding, but I want an accurate description.
@jsheunis, Should the descriptive text me something like:
"fmrwhy runs BIDS-compatible fMRI analysis with SPM12 and supports multi-echo data. It is no longer being actively maintained"

@handwerkerd thanks for the message, that is accurate yes. I'll update the repo with a similar note.
